The pump and 80 arm of the T-coupling and another section connected its motor are of a type now found in the open market with the elbow joint, whereby the flow pipe can be connected with the elbow joint and whereby the flow pipe can be disconnected from the elbow joint and shifted laterally away from the housing.

2. In a well, a well casing, an elbow joint rigidly secured to the well casing and in water tight connection therewith, a supply pipe leading from the well connected to one end of the elbow joint, a flow pipe extending longitudinally of the casing, a T-coupling interposed in the length of the flow pipe, and a slip joint having one section connected with the T-coupling and another section carried by the elbow joint whereby the flow pipe and the elbow joint can be inter-connected by moving one section of the joint over the other.

3. In a well, as defined in claim l, a sealing plug closing the flow pipe above the slip joint section carried by the T-coupling.

4. As a new article of manufacture a well casing section having a longitudinally extending opening therein, an outwardly projecting housing surrounding the opening and having water tight connection with the casing around the opening, and an elbow joint positioned in the lower end of the housing and rigidly secured to the housing in water tight connection therewith, said elbow joint being disposed wholly within the housing, leaving said casing unobstructed.
